x PETER DE MATTIA AND-SBARTHOLD DE MATTIA, OF CLIFTON, NEW JERSEY.

V'ULCANIZING-PRESS.

Application filed January 22, 1916.

To (ZZZ whom it'may concern."

'Be it known that we, PETER DE MATTIA and BARTHOLD DE MATTIA, both citizens of the United States, and residents of Clifton, in the'county ofv Passaic and State of New Jersey, have invented a new and Improvedulcanizing-Press,

of which the following and exact description. Among the principal-objects which the present invention has in view arez-to pro surrounding molds used in vulcanizing rubber articles; to providea press of the character mentioned with a'chamber for preventing the radiation of. heat from the edges of the molds and articles contained therein; to provide means for applying an expansive heating medium to the moldsand articles contained therein provide a simple, durable and eflicient cabinet and full-opening door therefor; and to provide a cross head having'a cabinet suspended therefrom.

Drawings. Figural is aside elevation of a press constructed and arranged in accordance with the present invention,

the lower portion of said figure being partly cut away in section;

forms, when cooperating 1g.- 2 is a top plan view of the same; ig. 3 is a vertical section taken as on the line 33 in Fig. 1, the view being shown on an-enlarged scale';

Fig. 4 is a horizontal section on the same scale, and taken on the line 44 in Fig.1.

Description.

As seen in the drawings, a cross head 9 is supported by a base 10 employing for this purpose stanchion rods 11. The base 10 is centrally perforated to form a bearing for the hub 12 of a bevel nut wheel 13, The hub 12 of the wheel 13 .is adapted to form therein an internal thread to register with' the thread of the screw section 14 of the plunger 15. Mounted on the end of the plunger 15 is a platform platen 16. The union between the platen 16 and the plungel 15 is made flexible, and employs a pin 17 extended through a tip 18 at the'end of said plunger, and a boss 19 pendent there- The element with which the platen 16 'cooperates, is a plate 20. The pl'ate'20 is integrally formed with the cross head 9,.and with the platen 16,

one of the two abutments between which the molds are pressed.

In the present invention, the plate 20 forms the top of a chamber 21, the side and bottom walls whereof are formed by the solid walled frame 22. The walls of the frame 22 are suitably reinforced by webs 23. i The frame is also provided with a bolting flange 24, through which the bolts 25 extend to engage the flange 26 of the cross head 9. When the bolts 25 are driven-home, the frame 23 is suspended from the cross head 9, andtogether with the plate 20 of the said cross head, forms the chamber 21. which is closed in service by the door27. The door 27 is provided with hinge braitkcts 42, which are pivotally connected by means of hinge pins 41, with brackets 43 set out from the frame 22. as shown best ,in Fig. 1 of the drawings. The door 27 is reinforced by webs 28, at the ends whereof are conprevents the escapement of steam delivered by the pipe'39, from the chamber 21. The pipe 39 may be connected with any suitable source of heating mediumsupply. While we may employ any suitable me icon, that are swung back, turning for this purpose on the pivot which is preferred and commonly used when vulcanizing rubber, is steam.
